In Figures 1 and 2, a tank is designated 1, and a firearm 2. The tank is made with Ieve~mounted wheels arranged in a way which is known per se so that ~he tank chassis can be elevated and depressed in relation to the ground. The firearm, which consists of a high-pressure gun with a calibre of 105 mm, is arranged so that it can be raised and lowered in relation to the tank chassis. The position indicated in Figure 1 in solid lines indica-tes the lowered position and the position indicated with the dot-dash lines
2 ~ the fully raised position of the firearm. The raising and lowering devi-ces are symbolized with the num~ral 3. In the lowered position, the firearm is traversed by turning the entire tank. In this position, the firearm is secured to the chassis with devices not shown in detail, in order to permit firing in the lowered position. These securing devices can comprise, for instance, hydraulic cylinders arranged in the tank chassis, the pistons of which coact with corresponding recesses in, for instance, the recoil jacket of the firearm. Elevation of the firearm in the lowered positon is control-led by means of the tank body.
The firearm is pivotally supported on the members 3 which can be raised and lowered in relation to the tank chassis. The carrier part of the - -pivotal support in Figure 2 is designated 5 and the trunnions which are located comparatively far to the rear on the carrier part are designated 6.
The breech ring on the firearm is designated 7. The members 3 which can be raised and lowered are made, in accortance with the following, so that the .
firearm can be traverset in relation to the tank chassis in the fully raised position. Since the pivotal support is located comparatively far to the rear of the tank, the breech ring, at a zero traverse position relative to the tank chassis, will be located substantially in line with the rear of the tank.
A first magazine part 8 is arranged at the rear of the firearm.
The lowered position of magazine parts is illustrated in Figure 1 in solid lines and the raised position is illustrated at 8' in dot-dash lines. The first magazine part is fastened to the firearm by two articulate fastening members in the form of hinges 9, which are located at the top of the first magazine part so that the magazine part in questinn can pivot upwardly in relation to the firearm. The normal position of the magazine part, as shown in Figure 1, is maintained by the end edges of the magazine part engaging with corresponding edges of the firearm when the weight of the magazine part urges it downwards around the hinge supports. Upwards pivoting of the first magazine part can be required when the magazine, can hit the ground, such as when driving in reverse, driving over ditches and the like, elevating etc.
The collapsible flotation screen of the tank is designated 11.
The magazine also comprises a second magazine part 12, connected - -to the tank chassis. This magazine part is an element separate from the rest -~
of the tank chassis, and is carried by articulate fastening devices 13 each of which consists of an arm 13a curved in the plane of Figure 1 and a suppor- :
ting shaftl3b. The arm 13a has one of its ends rigidly fastened to the top of the second magazine part and a through hole in its other end by which the arm is rotatably supported on the shaft 13b. In its centre the arm is pro-vided with a forked lug 13c for the piston 14 of an hydraulic cylinder 15.
The hydraulic cylinder is fixed to the tank chassis in a recess 16, which ~ ~
opens upwards in the tank, and into which the curved arm 13a extends for en- -gagement with the supporting shaft 13b. The forked lug and the hydraulic cylinder are positioned in relation to one an other such that the second magazine part can be pivoted relati~e to the tank chassis by means of hydrau-lic cylinder 15. The hydraulic cylinder is also controlled in such a way

1~4~ 0 that in the normal position (the position of Figures 1 and 2) of the second magazine part it permits upwards pivoting of the magazine part if external forces are exerted on the magazine due, for example, to collisions with the ground when driving the tank in reverse, driving over ditches, elevation of the firearm etc.
As will be noted from Figures 1 and 2, the second magazine part is suspended entirely freely behind the tank chassis and likewise the ma~or portlon of the first magazine part extends outside the tank. The second magazlne part extends along the ma~or portion of the width of the tank, whlle the first maeazine part has a more limited extent, in this direction, having a width which is about one-third of the width of the second magazine part. The articulate fastening members of the respective magazine parts are located at the corners of the parts in question. Each magazine part has a ; -height that permits it to contain two rounds placed one on top of the other.
In the lowered position of the firearm, the magazine parts can be engaged in a position where the magazines are connected internally with each other such that an automatic transfer of rounds can take place from the sec-ond magazine part to the first magazine part, which can hold, for instance, five rounds.
~he first magazine part can also be separated from internal con-nection with the firearm by means of a cover 17 that can be pivoted upwardly and, which in the uppermost position permits the passage of rounds and in the lowered position serves as a cartridge case deflector for empty car-tridge cases.
Figures 3 and ~ show the parts of a tank on ~hich the firearm is supported differently on the members 3. In Figure 3, thè support for the cover 17 has been designated 18. Support 18 is located at the top of the rirst magazlne part and consists of conventional hinge couplings. Control ~;
Or this cover can be carried out with the ramming devices of the firearm.
Figure 5 shows the operating principle o~ one embodiment of the -1~4Q9~0 raising structure 3. In this embodiment, the firearm is supported on a plate 19, in which the carrier part 20 of the pivotal support is mounted.
The firearm is supported on the trunnions 21 in the ~acket of the barrel 22.
The plate is arranged at the upper end of an inner cylinder 23, which is ro-tatably supported by the ball bearings 24 and 25 in an outer cylinder 26.
The outer cylinder is made with guides 27 which run in vertical grooves 28 in guide rails 29 fixed to the chassis 1.
Movement of the structure 3 in relation to the tank chassis is achieved by means of a hydraulic cylinder 30, which is fastened to the tank chassis at a fastening point 31 and to the underside of the plate 19.
Figure 6 shows the two magazine parts in a position where they are engaged. This is achieved with the aid of first covers 32, which are pivot-ally mounted on the roof of the second part. The hinges 33 for the first covers extend transversely of the part magazine (perpendicular to the plane --of Figure 6). The first magazine part is made with slide walls 34 inclined outwards from its top wall and against which the covers 32 can be pressed so that the two magazine parts can be locked together. The first covers are pivoted about hinges 33 by means of hydraulic cylinders 35. The covers are pivotable between a fully open position where the first magazine part with its wider bottom can pass between the covers and come into contact with the roof of the second magazine part, and a fully closed position where the first covers serve as covers for one or more openings in the roof of the second magazine part when the magazine parts are separated.
The second magazine part is divided into two compartments 12a and 12b, by means of a separating wall 36. In the compartments, rounds 37 are inserted in two rows arranged one on top of the other, the rounds in the rows then being separated into columns of two rounds each by means of separating walls 38. The separating walls can be actuated by means of lateral feeding device~ (not shown) for transportation of the rounds inside the second maga-z~ne part. The comp~rtments 12a and 12b have feed-out positions 39 and ~0 : ' ';
104~)910 respectively, for the rounds, towards which the successive columns of rounds are fed as the rounds in the feed-out position are pressed up into the first magazine part 8. As the feeding of rounds out from the second magazine part, progresses, the separating walls 38 are collected in spaces 41 and 42, res-pectively, intended for this purpose.
The pressing up of rounds into the respective feeding positions takes place by means of hois~ing devices including link arms which can be actuated by means of hydraulic cylinders at the bottom of the second magazine part.
Each hoisting device has three distinct positions, one of which, the rest position, is shown in Figure 6. In an intermediate position the upperone ofitAe two rounds of the columnhas been fed UPJ and at the end posi-tion, both rounds have been fed up.
Above the respective feed-up positions in the second magazine part, there are feed-out openings 44 and 45, respectively. The magazine parts ~-communicate internally with each other via these feed-out openings when joined together. Above each of the respective feed-up positions in the second magazine part the first magazine part has room for two rounds placed one on top of the other. The two rounds in this position are guided in guide members 46 and 47. Between the two pairs of rounds thus retained, there is also room for a fifth round in the first magazine part, above which members 48 for loading of the fifth round are arranged. Members 48, in the cross-section shown, occupy a space which substantially corresponds to a sixth round.
The first magazine part is also provided with a lateral displace-ment device 49 for each of the two pairs of rounds. In the enbodiment shown, the lateral displacement devices are made in the form of an angular part which extends in a direction perpendicular to the plane of Figure 6. The horizontal portion of the angular part is supported on swinging arms, by ~
means of which the angular part can be displaced laterally towards the fifth -rount position, The vertical portion of the angular part coacts with a round : ' 1~)4~)910 which is to be displaced laterally, and serves not only as a lateral dis-placing device, but also as a side support during loading. Blocking menbers 50 are also arranged on the support 47.
Filling up of the first magazine part can take place in such a way that a column of two rounds is first fed into the ~irst magazine part from either of the feed-up positions in the second magazine part, and the lateral displacement device 49 which serves the column of rounds which has been fed up is then activated so that the lower round is moved to the loading position ( the fifth round position) and is by means of the ramming members 48. There-after, the loaded displacement device is again actuated, so that the remaining round in the pressed-up column of rounds is moved to the loading position. -Retention of the upper round in the column of rounds is arranged so that the upper round does not drop into the lower round position until the lateral ^. ..... .
displacement devices have retùrned to the pick-up position. Thereafter, a -column of two rounds is fed up from each of the compartments in the second magazine part. The firearm can thereafter be actuated to its raised position, where six rounds can be fired before a new loading of rounds from the second magazine part is required. When rounds are fired in the lowered position, feeding can take place continuously from one of the compartments or alterna-tely from the two. In certain cases it can be an advantage to have the late-ral displacement in the first magazine part take place as soon as one of the two rounds in a column has been fed up into the first part, the hoisting device then retaining the remaining round in the column in its intermediate -position during this lateral displacement. With the embodiment shown, it is also possible to have a choice of ammunition types if the two compartments in the second magazine part are loaded with rounds of the different types. -In accordance with the above, the openings 44 and 45 can be covered - -~
